Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(18 + P + -2x2)' equal to zero and attempt to solve: Simplifying 18 + P + -2x2 = 0 Solving 18 + P + -2x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-18' to each side of the equation. 18 + P + -18 + -2x2 = 0 + -18 Reorder the terms: 18 + -18 + P + -2x2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + P + -2x2 = 0 + -18 P + -2x2 = 0 + -18 Combine like terms: 0 + -18 = -18 P + -2x2 = -18 Add '-1P' to each side of the equation. P + -1P + -2x2 = -18 + -1P Combine like terms: P + -1P = 0 0 + -2x2 = -18 + -1P -2x2 = -18 + -1P Divide each side by '-2'. x2 = 9 + 0.5P Simplifying x2 = 9 + 0.5P The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
